7000kw up to 12x12 room

http://www.appliancefactoryparts.com/search/part/1042383/116404 this is a link formthe extension cord you need.

the tonnage is found by taking the wattage of all equiment in the room to include the lighting utilising a formula to equate to btus. take this run a t-24 calc figuring all the factors window r factor, insullation, shading roof compasition, room facing direction etc. what system are you wishing a ductless split? motel unit? bard? split? heat pump? room unit? also electrical needs to be ran. figure a $1000 per ton contractor installed plus the electrical $500-750.

Hitachi is a good brand, I wouldn't be afraid of it.

As to the size, it seems a little 'oversized' for the room you're talking about.

24x12 = 288 sq ft. As a general rule you need 12000 btu for every 600 sq ft.

I'm thinking between 6000 -10000 btu ought to be big enough.

Lots of things go into sizing, and the size of the room is important - but the 'heat load,' needs to be considered too. For example - will there be a lot of people in this room, or is there a lot of windows, is there electrical equipment in this room that will be putting off heat, and how well is it insulated? So you need to consider all of these things when deciding what size unit to buy.

For example - if this room is a bedroom and used primarily for sleeping - I wouldn't be afraid to put a 6000 btu unit in it - but if it was going to be used as a place with tv's, computers and other electrical equipment I might want to put a 10000 btu (or larger) in it.

Good Luck!



Generally speaking, it sounds like 18000 btu is too much AC here, and there's no reason to spend more money than you need to and you can 'oversize' just as easy as you can 'undersize' when it comes to Air Condtioning.

The unit may not be big enough. From the model number I am thinking you a/c is a 12000 btu. Which is usally enough for a large room. However if you have an open floor plan or a really large room you may need a bigger or second unit.

DONT KNOW WHAT KIND OF MOTOR THIS IS BUT : IF THE MOTOR SAYS 115/230 VOLT AC ON THE INFO TAG AND IT HAS A LOW/ HIGH WIRING DIAGRAGM THEN YOU SHOULD BE ABLE TO CONVERT IT. SOME MOTORS HAVE A SWITCH ON THE FRONT FACE WHERE YOU REMOVE A SCREW AND ROTATE A SHAFT. IF THIS DOESNT HELP GIVE MORE INFO. JODY

Wiring manuals are available on CD $10-$15 from eBay, usually pirated.
